The 1.75 small fry hand pours really nice....easy. This mold is super easy to do a second color at the tail.
As for the twin-inject, I only hand pour for a second color.
They drop-shot really nice and, like Andrew, I use the VMC spin-shot hooks for this and I use either a size 6 or a size 4. I think Andrew does a size 8 in the spin-shot for sunfish.
Head weight for me depends on a couple of things. If I am dunking these under a float I use a 1/32 head weight cast on a #4 sickle hook. If I am casting and there is little wind I'll use the same head as under a float. If I am doing deep vertical or casting when there is some wind I use a 1/16 on a #4 sickle hook. If I shallow hook the plastic I can get by using a #6 sickle hook. As a rule I am one to use as large a hook as I can get away with and still hook fish. Sunfish might make me look to smaller hook size. Once in a great while I will tie on a 1/8 head with a size 4 hook cast into it if I am doing some serious current but I try to avoid the heavier heads.
Back to the 1.75 baits....the size [thickness] of the body makes this bait a dandy for color play using hi lites in transparent plastics. You work well with colors and you'll be able to create some wowsers I'm sure.
